3-3/4in DG/B In-Dash Tachometer

The AutoMeter 3-3/4in DG/B In-Dash Tachometer (Model 6399) is a digital Sport-Comp gauge built for drivers who need real-time engine speed monitoring with integrated shift light notification. This 10,000 RPM electric tachometer combines precision measurement with practical warning functionality, making it the choice for performance-oriented drivers managing their powerband during acceleration and gear transitions.

The gauge features a 3-3/4-inch diameter black face with digital display technology, delivering clear RPM readouts in varying light conditions. The shift light provides visual indication of optimal shift points, helping drivers maintain peak engine efficiency without relying on audible cues. The pedestal mount design allows flexible dashboard or console installation, accommodating vehicles with non-standard gauge cluster layouts. At 1.45 lbs with compact dimensions (6.6 x 5.1 x 7.2 inches), the unit installs cleanly without consuming excessive dash real estate.

This tachometer is purpose-built for street performance vehicles, track cars, and any enthusiast-level engine setup where monitoring RPM accuracy matters. Drivers who've upgraded their powerplants or operate outside factory gauge cluster specifications benefit from the Sport-Comp line's focus on reliability and legibility at high engine speeds. The shift light feature proves invaluable during spirited driving, reducing distraction and helping newer drivers learn optimal shift strategy without needless engine strain.

AutoMeter's Sport-Comp series represents the middle ground between economy gauges and competition-grade units, offering serious instrumentation without competition pricing. The digital display format appeals to drivers who prefer numeric precision over analog needle positioning, particularly in fast-paced driving where tenths of an RPM can matter.
